[mythtv-users] Re: Hardware MPEG2 vs bt878

[Baudouin, Andrew]

Actually, believe it or not...

All things equal a framegrabber will result in superior quality on-disk.
The problem lies with the quality of the tuner on the cheap framegrabbers.
It's clearly below that of the more expensive hardware cards.

To preserve quality ideally you'd like to have the raw video on disk and
compress it as you see fit rather than go straight into MPEG2.

I was already planning on having the bt878 only doing SVideo-in duty,
my direct analog tuner device was going to be a PVR-500 and i was
going to put in an ATSC tuner

I wanted screencaps of quality of PVR-150 or PVR-500 vs the bt878 - i
already know which is superior - i need to demostrate the superiority
to my fiance
